, referring to Fig. 2, controller is according to the effective Color control of mood light that processor is calculated for the hardware structure of the application
The color of the mood light that light source is sent.In the application, light source is at least one, and each light source is related to a screen subregion
Connection, forms logic corresponding relation, and the screen subregion is divided in advance by user, and each screen subregion can be with a light source
Correspondence can also be corresponding with multiple light sources, and correspondingly, processor calculates the effective color of mood light of each screen subregion, control
The effective Color control of mood light of the unit then according to each screen subregion light source corresponding with the screen subregion is sent
Mood light color.
In the prior art, the effective color of mood light is the master color of screen subregion, and this is under many circumstances unreasonable
, can preferably reflect vision atmosphere should be eye-catching color in screen subregion, that is, can most catch spectators' eyeball
Color.The principle of the application is the view data according to current screen subregion, therefrom obtains the eye-catching of screen subregion
Then color sends the atmosphere of corresponding color as the effective color of mood light according to the effective Color control light source of mood light for obtaining
Light.Specifically, Fig. 5 is a kind of flow signal of the effective color acquisition methods of mood light shown in the exemplary embodiment of the application one
Figure, as shown in figure 5, methods described includes：
Step S501, the image data acquisition sampling pixel points according to screen subregion, the screen subregion is drawn in advance
Point.

Step S501 reads the view data of each screen subregion according to the advance screen subregion for dividing, and view data includes each
The color-values of individual pixel.After reading the view data of screen subregion, if being clicked through using all pixels of screen subregion
Row is calculated, although can retain complete color information, but amount of calculation will be huge, to reduce amount of calculation, improving treatment effect
Rate, the pixel to screen subregion is sampled, and is calculated using sampling pixel points.To enable sampling pixel points to characterize
The color of screen subregion, is more preferably that the sampling that uniformly strides is carried out to pixel, and the uniform sampling that strides refers to the step of sampling
Width is fixed, the pixel number that the stride is separated by when referring to sampling between two neighboring sampling pixel points.Fig. 6 is uniformly to stride
Sampling two-dimensional example figure, wherein it is 3 to use sample stride, whole image represents a screen subregion, and each grid represents one
Pixel, wherein dark grid is sampling pixel points, is separated by three pixels between two sampling pixel points.If by pixel square
Battle array is converted to one-dimension array, then the sampling two-dimensional example figure that uniformly strides is converted to as shown in Figure 7 uniformly striding one-dimensional showing of sampling
Illustration.If all pixels point of screen subregion is：1920 × 1080=2073600, stride is 3, then uniformly stride and adopt
Sampling pixel points obtained by sample are 2073600/4=518400, and amount of calculation is reduced to 1/4, can largely improve
Computational efficiency and speed, correspondingly also improve the response speed of atmosphere photocontrol.
The color of multiple pixels adjacent in certain limit is not varied widely in general pattern, and technical staff can be with
Suitable stride is selected according to the required precision to color and computational efficiency requirement, it is to avoid stride is excessive to cause sampling pixel points
Color is representative not enough, and avoids the too small computational efficiency of stride from being difficult to improve.
Desired value sampling pixel points within a preset range are included into effective color pixel point set by step S502, described
Desired value is calculated according to the hue value of the sampling pixel points, and the preset range is average according to all sampling pixel points
Desired value determines.
The view data of screen subregion comprising pixel color-values, if the color-values include HSL (Hue form and aspect,
Saturation saturation degrees, Lightness lightness) value, then can directly read sampling pixel points after obtaining sampling pixel points
Hue value, while read the intensity value and brightness value of sampling pixel points, if the color-values only include rgb value
Or YUV values (Y represents lightness, that is, grey decision-making, and U and V represent colourity), then will be sampled picture using color space conversion algorithm
The rgb value or YUV values of vegetarian refreshments are converted to HSL values, so as to obtain the hue value of sampling pixel points.
In each color-values component of pixel, hue value can most reflect the boldness of picture element point chromatic, therefore main
Effective color pixel point set is calculated according to the hue value of pixel.Specifically, in one embodiment, such as Fig. 8 institutes
Show, step S502 can include：
(a1) the average index value of the sampling pixel points is calculatedWherein, n is sampled pixel
The number of point, V_k is k-th desired value of sampling pixel points, and V_k is calculated according to the hue value of k-th sampling pixel points
Obtain；
(a2) calculate the absolute difference Δ of the desired value with the average index value of each sampling pixel points=| V_k-V_
ave|；
(a3) absolute difference is included into effective color pixel point more than or equal to the sampling pixel points of predetermined threshold value
Set.
Wherein, the desired value of each sampling pixel points can be directly equal to the hue value of the sampling pixel points, such case
Under, step S502 is：
(b1) the average hue value of the sampling pixel points is calculatedWherein, n is sampling picture
The number of vegetarian refreshments, H_k is k-th hue value of sampling pixel points；
(b2) calculate the absolute difference Δ of the hue value with the average hue value of each sampling pixel points=| H_k-H_
ave|；
(b3) the absolute difference Δ is included into effective color pixel point set more than the sampling pixel points of predetermined threshold value.
Wherein, if the absolute difference between the hue value of sampling pixel points and average hue value is more than predetermined threshold value,
It is eye-catching pixel to regard the sampling pixel points, is classified to effective color pixel point set, by adjusting the predetermined threshold value, can
To adjust eye-catching detection level, predetermined threshold value is bigger, and the color of the pixel in effective color pixel point set is more eye-catching, but picture
Vegetarian refreshments number diminishes, and can reduce the degree of accuracy of effective color, and technical staff can combine boldness requirement and effective color is accurate
The requirement of exactness selects suitable predetermined threshold value.
Except according to single hue value come calculate each sampling pixel points desired value in addition to, it is also possible to by hue value and saturation
Angle value is combined, or hue value combined with brightness value, or hue value is combined come described in calculating with intensity value and brightness value
Desired value, so as to be calculated effective color pixel point set.For example, setting one Classification Index V=a*H+b*L, wherein a are
The weight coefficient of hue value, b is the weight coefficient of brightness value, calculates the average index value of sampling pixel pointsV_k is k-th desired value of sampling pixel points；The desired value of each sampling pixel points is calculated again
With absolute difference Δ v=| the V_k-V_ave | of the average index value；Then by the absolute difference Δ v more than default
The sampling pixel points of threshold value are included into effective color pixel point set.The average index value can be then all sampling pixel points
The arithmetic mean of instantaneous value of desired value, such as calculating of above-mentioned V_ave, the desired value can also be the desired value of all sampling pixel points
Weighted average, sampling pixel points are for example divided into several parts, per partly assigning different weighted values, then calculate all adopting
The weighted average of sample pixel, is average index value with the weighted average.
Step S503, is calculated corresponding with the screen subregion effective according to effective color pixel point set
Color.
After the effective color pixel point set for obtaining, can with effective color pixel point set all pixels point it is average
Color-values are the color-values of effective color, that is, effective color j-th color component value
Wherein, m is the number of pixel in effective color pixel point set, Cj_ i is the in effective color pixel point set
I j-th color component value of pixel, j is natural number and 1≤j≤t, t are the number of color component.The color component
Can be RGB color component, or HSL color space components.It is described effective by taking HSL color space components as an example
The hue value of colorIntensity valueAnd brightness valueWherein, H_i is the hue value of ith pixel point in effective color pixel point set, S_i
It is the intensity value of the ith pixel point, L_i is the brightness value of the ith pixel point.Can not also use simple and easy to apply
Arithmetic mean of instantaneous value calculate each color component, and calculated using other mean algorithms.
After the color-values for obtaining effective color, effective color is just determined.Controller is according to each screen being calculated
Effective Color control light source corresponding with the screen subregion of curtain subregion sends corresponding mood light, realizes display device
Atmosphere optical illumination when playing.The effective color acquisition methods of mood light provided herein, adopt to all pixels point
Sample, calculates effective color and improves computational efficiency, and include hue value according to sampling pixel points using sampling pixel points
Color-values carry out pixel and divide to obtain effective color pixel point set, compared to existing technology in master color be effective color
Method, technical scheme provided herein more considers the boldness of color such that it is able to improves effective color and obtains
The degree of accuracy for taking, realizes more preferable atmosphere light effect.
Fig. 9 is that the flow of the effective color acquisition methods of another mood light shown in the exemplary embodiment of the application one is illustrated
Figure, as shown in figure 9, methods described includes：
Step S901, the image data acquisition sampling pixel points according to screen subregion, the screen subregion is drawn in advance
Point；
Desired value sampling pixel points within a preset range are included into effective color pixel point set by step S902, described
Desired value is calculated according to the hue value of the sampling pixel points, and the preset range is average according to all sampling pixel points
Desired value determines；
Step S903, is calculated corresponding with the screen subregion effective according to effective color pixel point set
Color；
Step S904, the master color of screen subregion described in the image data acquisition according to the screen subregion is described
Master color is to occupy the most color of pixel；
Step S905, the intensity value of relatively more described master color and the intensity value of effective color, and compare institute
State the brightness value of master color and the brightness value of effective color；
Step S906, if the intensity value of the master color is more than the intensity value of effective color, and the master
The brightness value of color, more than the brightness value of effective color, is effective color with the master color.
Wherein, step S901 to step S903 is identical with step S501 value steps S503.Shown in method shown in Fig. 9 and Fig. 5
The difference of method is, being calculated effective color pixel point set according to the hue value of sampling pixel points, and then calculates
It is not final mood light color with effective color to after effective color, but further obtains the master of sampling pixel points
Color, then effective color and saturation degree and lightness both master color, if the saturation degree and lightness of master color
All higher than the saturation degree and lightness of effective color, illustrate that master color is calculated compared to according to the color-values comprising hue value
The effective color for obtaining is more bright-coloured and brighter, therefore abandons the effective color being calculated before, is final have with master color
Effect color.Because the main effective color calculated according to the hue value of sampling pixel points, may be because of sampling stride
The calculation error of the incorrect and average value chosen with predetermined threshold value etc., causes the accuracy of effective color, is more accurate
Effective color really is obtained, after the method according to Fig. 2 is calculated effective color, is determined most further combined with master color
Whole effective color.
Wherein, the master color is in the image of screen subregion to occupy the most color of pixel, due to visually phase
Slight difference is might have with the actual color-values of the pixel of color, therefore can be with preset color value deviation range, then
The color-values of statistical screens subregion all pixels point, the color-values pixel in same color-values deviation range that falls is considered as
Same color pixel point, and the ratio that the number of same color pixel point accounts for all pixels point number is counted, with proportion most
Big same color pixel point is main color pixel point, then calculates the averaged color value of master color pixel, obtains master color.
If the color-values of pixel only include rgb value in the view data of screen subregion, after obtaining master color, by its rgb value
HSL values are converted to, the intensity value and brightness value of master color is obtained.
Wherein, the step of obtaining the master color can also perform before step S801, or with step S801 simultaneously
Perform.
